11 Claims.

This invention relates to baking pan sets generally and to the straps by which the individual pans of the set are joined together to create a multiple unit pan set. Among its other objects, the present invention contemplates a strap which incorporates elements to guide or center the pan sets, thereby regulating and determining their respective positions when two or more are nested or stacked for storage purposes. It furthermore has in view the maintenance of the nested or stacked pan sets in such spaced relationship as to prevent the marking or marring of the interior surfaces of pan walls and to provide an increased air circulation between the nested or stacked sets.

With the above and other objects in view, as will be apparent, this invention consists in the construction, combination and arrangement of parts, all as hereinafter more fully described, claimed and illustrated in the accompanying drawing, wherein:-

Fig. 1 is a side elevation of the several pan sets embodying the present invention in the stacked or nested relationship;

Fig. 2 is a vertical section taken along line 2-2 of Fig. l illustrating the cooperation between the straps and coacting elements upon stacking several pan sets;

Fig. 3 is a fragmentary side elevation of portions of two pan sets nested illustrating a modified form of the present invention.

Fig. 4 is a vertical section taken along line 4 4 of Fig. 3.

Baking pan sets consisting of a plurality of individual baking pans secured one to the other in various ways and by various means to create multiple unit pan sets are well known in the art. After use such pan sets are usually stacked in relatively tall piles or stacks by nesting one set within the other. during this stacking and nesting, the exterior walls of the pans of one set contact with the interior faces of the walls of the pans of the set within which it is nested, it frequently mars or discolors the inner faces of the walls of the receiving set which discoloration is citen transferred to the material baked within the pans. Furthermore, it has also been found that when a stack of nested pan sets becomes somewhat attenuated there is an inclination for the pans to move relatively in a horizontal direction and such movement frequently destroys the vertical alignment of the stack and causes it to lean or tilt one way or the other. Also, it is desirable when pan sets are stacked, which usually occurs when they are warm It has been found that when,-

or hot, to provide sufficient space between the elements of the stack and between the units of the several vsets to permit air circulation so that the sets cool uniformly and at the same time prevent the walls of the pans of the stacked sets 5 from contacting at any point.

The present invention contemplates a pan set made up of individual pans combined into a multiple unit set by a strap or straps combined to form a frame encircling the pans of the set contacting with and secured tothe exposed walls of the pans of the set. The strap or straps, of course, may be secured to the walls of the pans in any suitable manner and may be of any suitable construction. It is, however, contemplated to incorporate in the strap or frame a means whereby the pan sets when nested and stacked are/prevented from having any lateral or relatively horizontal movement thereby creating a firm and rigid stack, the individual members of which are held against relative movement so that `'the stack is constantly vertical. The construction of this strap is such that when nested the walls of `the units incorporated in the several stacked or nested pan sets are held in spaced relationship thus providing an air gap as well as preventing the discoloration of the interior faces of the walls of the pans of the sets.

In other words, the present invention proposes a nesting guide or guides carried by thestraps of the individual pans which in itself does not contact with the tin plate of the individual pans of the set and holds the sets against relative movement, when in a stack, and at the same time maintains the lwalls of the pans of the sets within the stack in spaced relationship providing for Van air `circulation between the pans of the sets and preventing any discoloration or marring of the inner facesrof the walls ofthe individual pans of the set.

Reference being had more particularly to the drawing, `II'I designates a plurality of pans of any suitable lform or construction which are combined to create a pan set. At the upper edges of the walls of each individual pan I are the flanges I I which are bent outwardly and downwardly about a wire frame I2 to Vcreate an outstandingbead at the edges of the walls of the pan. It will be observed that at the corners of each individual pan I0, the wire `frame I2 is exposed and not 50 covered with the flanges II. This is not essential as in some types of Vpan sets the wire frame I2, `or its equivalent, is covered at all points including its corners by the anges of the pan I Il. However, as will be apparent, the exposed wire frames I2 when they are present in the pan set are the elements which receive the brunt of the contact in the present invention and where the frames I2, or their equivalent, are completely covered, it is at the corners of the individual pans and upon the outer surfaces of the corners that the present invention acts.

In that form of pan sets disclosed inthe drawing, the individual pans IG are held together by a strap I3 positioned along and against the exposed end walls of the pans I0. This strap I3 may be part of a frame extending completely around the pans I5 of the set, or it may be one of two or more straps, one upon each side of the set and each bearing against and secured to the exposed end walls of the pans combined in the set. The mounting, and to a large extent, the construction of the straps I3 and the cooperation thereof with the pans, have no particular bearing upon the present invention. In that form of strap I3 shown in the drawing, a bead I4 is formed along each longitudinal edge of each strap I3, the upper bead being positioned below the outstanding beads formed by the frames I2 at the upper edges of the walls of the pans I, while the lower bead I4 is remote from the upper bead I4 and is positioned medially of the height of the end walls of the pans I0 of the set.

Positioned to correspond to and align with the spaces between the pans I0 of the set are one or more teats or lugs I5 formed from the lower edge of the strap I 3, and in that form of the strap shown in the drawing, form the lower bead I4. This lug or lugs I5 project below the line of the lower edge of the strap I3 and are of a width substantially equal of the space between the beads at the edges of the walls of two adjoining or adjacent pans of the set. In that form of the invention shown in Fig. 1, a relatively short reinforcing bead I6 may be formed from the body of the strap above each lug I5 and approximately parallel to the lower bead I4, thereby reinforcing the strap I3 at the point or points where the lug or lugs I5 are formed therefrom. It is to be observed that the number of downwardly projecting lugs I5 provided along the vlower edge of each strap I 3 depends entirely upon the length of the pan set, so that while two are shown in Fig. 1 of the drawing, any number of lugs may be provided: either one for each space between adjoining pans ID of the set, or one for each alternate space between adjoining pans of the set.

When a plurality of pan sets, such as illustrated in Figs. 1 and 2 of the drawing, are nested for the purpose of creating a stack, the lugs I5 of reach pan set enter the spaces between the adjoining pans of the set positioned below ity and occupy substantially all of said spaces at the points corresponding to the corners of the pans I9 combining to make the set. If the wire frames I2 are exposed at the corners of the pans Ill, which is the case in that form of the pan shown in the'drawing, the-lugs I5 operate against and approximately contact the exposed corner portions of the wire frames I2. vAs the lower edges of the straps I3 of the upper set rest upon the beads of the pans I0 of the set below, it is manifest that the lugs I5 extending below the lower edges of the straps I3, extend into and occupy the spaces between the pans I0 of the lower set and thereby prevent any llongitudinal movement of the set of the stack relatively one to the other. This prevention of the longitudinal movement of the pan sets also prevents any contact between the walls of the pans IIl'offthe several sets thereby avoiding any discoloration of the tin plate or the marring or spotting of the inner surfaces of the walls of the pans I. Furthermore, with such an arrangement there is ample air circulation between the pans of the sets and there is no 5 inclination of the stack to tip or lean in any direction out of the vertical.

The modification of the invention disclosed in Figs. 3 and 4 operates in substantially the same manner as that form of the invention shown in 10 Figs. 1 and 2. The strap I3, at its lower edge in alignment with the space between pans, is provided with a downwardly extending lug I5 formed from the strap at the lower bead I4. In order to reinforce and strengthen the strap I3 at this 15 point, the strap is enlarged or bulged outwardly above the bead, as at I6', in alignment with the lug I5" transversely of the strap I3. This lug I 5', when the pan sets are stacked, operates exactly as does the lug I5 in the form of the invention 20 shown in Figs. 1 and 2. Formed from the strap I3 and on the upper edge thereof, is a second lug I'I aligned transversely of the strap I3 with the lug I5. It will be observed from Fig. 4 that thel teat or lug I5' is formed outwardly from the 25 strap I3 and may be said to form a continuation of the highest point of the bead I4. On the other hand, the lug or teat Il is in alignment with and forms a substantial continuation of the body of the strap I3. Thus, when the pans are stacked, 30 as illustrated in Figs. 3 and 4, the teat or lug II of the lower pan set is received at the rear of the lug I5 of the upper pan set. In this manner, the lugs or teats I1 provided upon the several pan sets of the stack act as guides cooperating with 35 the teats or lugs I5' to insure the proper positioning of the several teats or lugs I5'.

It is manifest from the foregoing that the principal feature of the present invention is the provision of a member aligned with a space between two pans II of a set that will enter and be seated 40 in a like space of a set in which the first set is nested at a point adjoining the corresponding corners of adjacent pans. Such an element or member obviously does not depend upon the construction of the pans or upon the manner and means by which the pans are secured into a set.
